It made my entire face puff up and look awful. At least, that's how I remember it, it was about twenty years ago :o
I feel your pain; Zyrtec seems to be less and less helpful for me as time goes on, and yeah, something like Benedryl puts me right to sleep as well, which I learned the hard way when I tried taking some during a particularly bad episode at work once... (fun fact I discovered later: Benedryl and Tylenol PM share the exact same ingredient.)
I'd love to look into allergy shots at some point but they're expensive! :x
